Overview

The hub-rest-api-python provides Python bindings for Hub REST API.

Paging and Black Duck v2022.2

In v2022.2 of Black Duck the REST API introduced a max page size to protect system resource usage. See the Black Duck release notes on Synopsys Community for the details of which API endpoints are affected. Users of the the python bindings here should leverage the Client interface which provides automatic paging support to make best use of these endpoints.

The old HubInstance interface and many of the examples using it do not perform paging and will break as a result of the changes in v2022.2.

New in 1.0.0

Introducing the new Client class.

In order to provide a more robust long-term connection, faster performance, and an overall better experience a new Client class has been designed.

It is backed by a Requests session object. The user specifies a base URL, timeout, retries, proxies, and TLS verification upon initialization and these attributes are persisted across all requests.

At the REST API level, the Client class provides a consistent way to discover and traverse public resources, uses a generator to fetch all items using pagination, and automatically renews the bearer token.

See Client versus HubInstance Comparison and also read the Client User Guide on the Hub REST API Python Wiki.

Important Notes

The old HubInstance (in HubRestApi.py) keeps its existing functionality for backwards compatibility and therefore does not currently leverage any of the new features in the Client class.

We believe that the new features are compelling enough to strongly encourage users to consider moving from HubInstance to Client. See Client versus HubInstance Comparison.

To use

pip3 install blackduck

from blackduck import Client
import logging
import os

logging.basicConfig(
    level=logging.INFO,
    format="[%(asctime)s] {%(module)s:%(lineno)d} %(levelname)s - %(message)s"
)

bd = Client(
    token=os.environ.get('blackduck_token'),
    base_url="https://your.blackduck.url",
    # verify=False  # TLS certificate verification
)

for project in bd.get_resource(name='projects'):
    print(project.get('name'))

Examples

Example code showing how to work with the new Client can be found in the examples/client folder.

Test

Using pytest

git clone https://github.com/blackducksoftware/hub-rest-api-python.git
cd hub-rest-api-python
# optional but advisable: create/use virtualenv
# you should have 3.x+, e.g. Python 3.8.0+

pip3 install -r requirements.txt
pip3 install .
cd test
pytest
